Multiple destination trip participation has been rarely explored in the field of tourism demand studies in spite of its importance. This study investigates the determinant factors of multiple destination trips participation using a logistic regression model. Data were collected from 812 visitors to Seorak National Park on January 2009. Results indicated that the rate of the multiple destination trip participants was about 84% among the samples. Results also showed that travel distance, overnight stay, use of personal car made statistically significant effects on multiple site visit.. Particularly, results demonstrated that the rate of multiple destination trips participation was tend to be increased continuously when the participants travel distance exceeded 175km.
